Yes. You should use the software that best combines familiarity and flexibility and matches well with your personal workflow. I can't be more specific than that because software that is suitable for a beginner who wants to drop some symbols, text, and lines but will never touch that map again is most likely completely different than software used by a well-practiced and talented pro who is doing a series of maps based on a specific style and setting.
